DLG Test Center redesigns feed certification to include nitrogen, phosphorus footprint


In order to meet new requirements on the testing side, the Test Center Technology and Farm Inputs of the DLG (German Agricultural Society) has redesigned its approach to feed certification, the Center said in a press statement. The first test contents have been presented for the certification of nitrogen and phosphorus reduced feed as a pilot group, which will also in future conclude with the award of the DLG quality seal. Further focal points will follow shortly.

In the course of increasing demands on the quality and traceability of food of animal origin, the entire value chain is confronted with ever increasing requirements and significantly increasing complexity of demands. This means that feed nowadays not only serves to meet the demand of the animals, but also has to guarantee their health and performance. Furthermore feed is the basis for an environmentally and animal-friendly production of food, for safety and quality in the value chain and for the profitability of the agricultural operation.

"With the reorganisation of DLG's feed certification, we are taking into account that, unlike in the past, feed in animal husbandry is no longer just a guarantee of high performance by means of optimal nutrient supply for the animals," says Sander Schwick, test engineer for feed certification at the DLG-Test Center.

Dr. Michael Eise, division manager for all tests of farm inputs, adds, "By using modern feed we're able to and we also have to meet higher animal welfare requirements in the future. Additionally, in terms of environmental protection, we can have a very positive effect on nutrient output from the stalls. All these aspects were taken into account, when we completely redesigned our test regulations."

Stefano Mastrogiovanni, managing director of the DLG Test Center, rates the strategic realignment of DLG feed as positive. He says: "With this new, modular test structure, we will be able to react much faster to changing market requirements in the future, as we only need to add these special test criteria to the test framework and not have to completely revise it."

Nitrogen and phosphorus-reduced feed guarantees that the animals are optimally supplied with protein or amino acids and phosphorus while at the same time the excretion of nitrogen and phosphorus via faeces and urine is maximally reduced. The possibility is up to 20% less nutrient output from the stable and thus can lead to a significant reduction of nitrate pollution into the soil and groundwater without burdening the animal owner with immense costs.
